The eu.com is a sub-level domain explicitly for European companies, because it demonstrates clearly a commercial orientation in Europe, which can be seen directly in the domain extension. Just internationally operating companies buy and register usually one single domain name with various Internet country code top-level domains to be represented on every national market. Thanks to the eu.com, from now on companies are able to demonstrate a European commercial orientation with only one domain.
There are no requirements that must be met to buy and register an eu.com domain. Only the domain name must meet several conditions: Total available are between 3 and 63 characters, numbers within the domain, special characters and pure numeric domains are of course permitted.
As alternative, many Internet country code top-level domains exists: It is very comfortable to buy and register for example the official Internet country code top-level domain of Denmark with extension .dk, the French .fr domain or even the German top-level domain .de - all these domains you could find in the portfolio of easyname.
The competent registry CentralNic offers a portfolio of 27 different domains including the eu.com domain, the uk.com, the com.de, the us.com and the cn.com domain. According the CentralNic extension eu.com enjoys a great popularity: Only in England the company recorded in the first week more than 5,000 newly registered eu.com domains.
